I got it installed in Upup Precise. I launched it in console and then I added the packages and python modules according to error messages.
It started in tray. I created an account and then It tried to contact webcam...and hanged there. I didnt test it more.

Oh yes. It needed symlink, /usr/bin/sensible-browser. I symlinked /usr/local/bin/defaulbrowser to point that and browser launched from tray app after that.
